The king betta is a beautiful-looking fish. This type of betta has blue, green, and yellow colors in its body which makes it really eye-catching. The male fish can grow up to four inches while the female only reaches about three and a half inches long. King Betta’s live for about five years which means that they are a great pet fish to have in your home.

Origin and distribution

Betta fish are originally from Southeastern Asia. They can be found in India, Sri Lanka, and Myanmar (Burma). There is a high level of variability within the wild population as they adapt to different environments such as slow-moving rice paddies or stagnant water with dense vegetation and mud at low altitude areas. The most popular type of betta fish, Betta splendens or the Siamese fighting fish, is bred in captivity and most likely originated from a cross between wild populations.

The word “bettas” comes from the Malay language meaning “ugly”, as they were thought to be ugly compared to other types of aquarium fishes. Today these colorful creatures are popular as pets in the aquarium hobby.

In their natural habitat, Betta fish are most commonly found around rice paddies and other still or slow-moving water sources at low altitudes with heavy plant coverage such as overgrown weeds and grasses. These plants offer good protection from predators while also providing shade from direct sunlight which would otherwise prove lethal for the fish.

Species profile

King Betta is an omnivorous freshwater fish, native to the Mekong River basin in Southeast Asia. They live on a diet of insects and small invertebrates such as worms, which it scrapes from underwater plants with its pointed lower jaw.

Bettas are also known as Siamese fighting fish because when they fight, they lock together and turn themselves upside down or sideways to make biting difficult for their opponent. Bettas will continue to attack each other until one of them gives up; however, this can lead to serious injury or even death. Males are typically more aggressive than females and have a longer, wavier filament on their tails.

Their natural habitats are rice paddies and shallow water gardens where they can be found swimming in schools, but the King Betta is also an important food fish for humans. They’re a common ingredient on menus at restaurants that specialize in Thai cuisine because of their meaty texture when fried or grilled with other ingredients such as garlic, onions, lemongrass, ginger, and chilies.

The King Betta is a popular fish with aquarium enthusiasts because of its bright colors which are derived from pigments in the water where they live along with their hardy nature that makes them easy to care for. The males show off these colors by displaying fins that span between reds, oranges, yellows, blues, and whites.

Bettas come in many different shapes and sizes; however, the most popular variety among hobbyists is a long-bodied fish with a large head called Halfmoon Betta or Marble Eye Betta. The scales on these are so small that they appear as marble eyes throughout their bodies when lit from underneath. This variety is so popular that it has led to many different color mutations, such as blue eyes and split-colored scales.

Color and appearance

King betta fish are typically yellow with brown or black stripes, however, there can be some variation in color and appearance. The body is usually brownish-gold while the fins are deep red-brown.

Range and habitat

The natural habitat of the King Betta fish is in Thailand and Malaysia. They are found near stagnant water sources like ponds, rice paddies, or drains that release into a larger body of water. These betta enjoy living close to these bodies of calm waters because they have no natural predators there. This makes their habitats one more thing for them to worry about.

The King Betta is extremely territorial due and a single specimen will claim the entire body of water as its territory, fighting off any other fish who tries to invade the area. They are also very aggressive towards their own species which can lead to death if they cannot be separated from each other for too long. In addition, the King Betta is a carnivore which means it must have meat to survive. This gives them an advantage over other fish in their habitat because they can hunt for food instead of waiting for prey items to come by.

King betta fish size

The king betta fish is a freshwater species that can grow up to about 4 inches in length.

How big do King bettas get?

They’re typically about 4 to 5 inches long, they live the typical life span of 3 to 6 years with a range from 2 to 10 years in captivity; most commonly living for around 5 or more years

What size tank does a king Betta need?

The minimum size for a king Betta is 30 gallons. The tank needs to be at least 20 inches in height. A small aquarium with these specifications can work if it does not have any other fish or live plants that are incompatible with the betta’s requirements and you do not plan on having more than one king Betta per tank. If you would like to have more than one king Betta per tank, plan on using a larger aquarium or upgrading in the future to accommodate your growing number of bettas.

Life cycle

A female betta will lay up to 20 eggs at a time, usually on the underside of water plants. The eggs are sticky when they first come out. After about 24 hours, they turn into fry and start swimming freely around the tank. If no male is present in the fish tank, or if there are too many females for one male, then the eggs will not be fertilized and they will die.

Fry should be fed live food twice a day for up to six weeks before being transferred into its own home aquarium.

King betta fry has a high mortality rate if not cared for properly but otherwise grows normally with careful feeding practices.

Are King Bettas more aggressive or peaceful?

King betta fish are generally considered an aggressive type, but they can be trained and tamed to live in a community aquarium or alone. The key here is that the king betta needs time to adjust to its new environment before it will show any signs of aggression – so patience is important when introducing this pet fish into your home.

The Betta fish is a carnivorous, freshwater member of the gourami family. The ideal water temperature for bettas ranges from 78-86 degrees Fahrenheit and they can only live in fresh tap water with no other inhabitants due to their territorial nature. Bettas thrive on live or frozen foods like blood worms, daphnia, and brine shrimp. Bettas are known for their long, flowy fins that can be a variety of colors and patterns depending on the breed type.

You must mist your betta tank with purified water every day to keep them healthy. When it comes time to clean out the excess waste in your container, you should use dechlorinator that will neutralize the harmful chemicals in your water.

When it comes to cleaning, you should also be aware that bettas are sensitive to strong soap or detergents and they need a high level of oxygen. You can clean their container with fresh water which is why we recommend keeping them out of any other tank where there might not be ample oxygen.

You can use a plastic net to remove any debris that has built up in the container and wiping down the sides of the bowl with a cotton swab dipped in fresh water will help keep it clean!

What they eat

Bettas are carnivores. They will eat anything with meat in it, including blood worms and brine shrimp (the staple of many betta keepers). There is a strong belief among some people that since they come from the water they must be vegetarians. This isn’t true! Bettas can survive on fruit juice or a vegetable diet, but they prefer meat.

King betta tank mates

Betta fish are notoriously territorial and should not be housed with other bettas, or any other species of fish. A tank that is too small will lead to aggression and fighting. Male bettas can sometimes live together if they have a lot of space, though this is not the best option for most hobbyists due to the high risk of fighting.

Water condition

A betta fish needs to live in water that is not too cold, but not too warm. The ideal temperature for a betta’s tank is about 78 degrees Fahrenheit. If your home has an unusually cool or hot climate, you may need to adjust the thermostat on your heater and air conditioner so it stays within this range.


In the wild, king betta (Betta splendens) live in large aggregations of males with females. The female will lay her eggs on a rock or plant above this fray and have them fertilized by one to five out-competing males while the other males guard their territory. Once she releases her spawn, she gathers it up into her mouth and heads to a hiding place.

In captivity, the female will lay eggs in a container or vase with plants for the substrate. Females should be given time after laying their spawn before being bred again because they need some time to rest and recover from egg-laying, which is very stressful for them. The male may fertilize her eggs and guard the nest or he may also wait until she is done laying, then fertilize.

The fry will hatch in about 24 hours if they have been kept at a constant temperature of 28-29 degrees Celsius. The male should be removed from the tank once spawning has occurred because he can eat all the eggs that are not fertilized.

The lifespan of a king betta can depend on the care it gets as well as its own genetics. Some fish are more prone to illness, and less able to fight off infections than others. These factors influence how long an individual lives in captivity or out in nature. King bettas that live under good conditions may have lifespans of up to 3 years.

Parasites and diseases

Parasites and diseases are the most common reasons for fish deaths in aquariums. A parasite is a small animal that lives on or inside of another larger organism, called its host. Fish sometimes get parasites from eating other organisms such as worms or coral polyps, which contain larval stages of certain types of parasitic animals. Diseases are caused by infections and can include bacterial, fungal, or viral pathogens.


Predators of the king betta are other fish and loaches. The dragon goby is a common predator that can attack it from out in the open water, but they sometimes also come up into vegetation to prey on them as well. Their predators vary depending on where their habitat is found.

Does it make good pets?

No. King bettas are not a good pet to have because they require more care than most fish.

King betta male

The male of the species is usually smaller than his female counterpart. Generally, males have a blue and white bar pattern on their heads near the nose. Males are generally active during daytime hours while females tend to be more nocturnal in nature. The males also possess a dorsal fin that can extend up to two-thirds of their body length.

King betta vs giant betta

The King betta is a hybrid of the American and Asian Betta. It has long, flowing fins that are pointed at the ends. The body color can be any number of combinations like blue-green with red, orange black stripes, or yellow/brown with dark green striping. They have two rows of spiky fin rays on their dorsal fin and are considered the most popular Betta.

The Giant betta is a type of wild-caught fish that comes from Burma (Myanmar). They have very short fins with round tips, deep blue or black body colors like red dots on their dorsal fin, and other patterns below them. They’re also known as “Dirty Bets” because of their dark body colors.

The King betta is the more common and popular type, while the Giant is much less common but still a very beautiful fish to look at in an aquarium. Both types are said to be active during daylight hours which makes them both perfect for children who want to see them swimming around all day.

Halfmoon king betta

Halfmoon King betta fish is one of the most popular types in the aquarium hobby. This is because they are very active and easy to keep as long as their tank has lots of plants, rocks, and wood for them to hide among. Halfmoon king betta requires a 30 gallon or larger tank with an area at each end that is about half the tank’s length. The water quality should be kept constant with a temperature between 72 and 82 degrees Fahrenheit, although they are tolerant of warmer or cooler temperatures outside this range.

They need good filtration but will not thrive in heavily planted tanks. King betta fish have been bred to different colors like red-golden, red-orange, gold, or copper.

Halfmoon king betta fish need a varied diet of live and frozen foods like bloodworms, mosquito larvae, brine shrimp, daphnia; as well as dry food in the form of flakes or pellets. To keep them healthy, they should be given supplements such as spirulina to ensure their diet is complete in vitamins and minerals.
